The Mars colonization thing is worth so little that it’d eclipse everything else and make the company worth negative dollars, if he ever really puts them all in on it. It’s pure fantasy. Mars sucks. It sucks very, very, very much. It sucks more than a nuclear-holocausted Earth that’s also had a decent size (but not crust-liquefying) impact and an insanely bad climate disaster, at once. It’s an awful place.
